versatility . ability
to burn any fuel... ability to deliver effi ciently far beyond rated capacity... makes this boiler ideal for any medium size building. Kewanee Type R Boilers are giving economical, trouble-free service in thousands of office and store buildings, schools, motels, hospitals, small factories, etc.
It operates at top efficiency with oil, gas, or coal. Coal may be hand or stoker fired. Change from one fuel to another, or from mechanical to hand firing, or back again, can be made quickly, inexpensively.
Teamed with radiant baseboards, wall, floor or ceiling coils or panels, convectors or conventional radiators, Kewanee Square Heat Type R provides a sturdy steel heart for the system. It can be pushed far beyond rated capacity yet operate at full efficiency.
The result of nearly a century of experience, this boiler offers the medium size building all the heating dependability and economy for which Kewanee Boilers have always been famous.
A.S.M.E. and S.B.I. Code requirements have been followed to the last detail. But more than that, Kewanee guarantees per formance well beyond any code requirements.
three pass design
Kewanee 3 pass design assures maximum heat transfer from fuel to water. The large firebox provides complete mixing of fuel and air. Combustion is complete--all fuel burns-before the hot gases enter the fire tubes. In the first pass gases travel from front to rear in the firebox. The second pass is from rear to front in the bottom bank or direct tubes. The third pass is from front to rear in the return tubes. This longer gas travel transfers maximum BTU's to water.

Note these features.
The husky shell tells of extra sturdiness, insideyou see the many features that pack so much efficiency into compar atively small space.
At every level of rated capac ity ... even at loads far above nominal ratings . . . Kewanee Square Heat Type R operates at full efficiency.
Hydrostatically tested at 60 psi, it operates up to 15 psi steam or 30 psi hot water.
The smoke hood has two cleanout openings and a cir cular rear outlet that fits standard size smoke pipe.
Coil opening provides for in stallation of either tank type or instantaneous water heat ing coil.
Steel flue access cover with insulation securely keyed in place. (Stoker and hand fired boilers have cast iron flue doors and frames).
Spinner blades in oil-gas boilers 3R1 to 3R8 inclusive . . . swirl hot gases against tube walls assuring maximum heat transfer.
Shell is extra heavy, quality steel plate for strength and dependability.
Insulated cast iron fire door. Stoker and hand fired boilers have cast iron fire doors with liners and door slides for sec ondary a ir.
Cleanout openings with hollow brass plugs and rubber gaskets located at each corner.
150 lb. American Standard flange on Nos. 3R9 thru 3R12.
High and abundant steam space assures ample reserve of dry steam.
Disengaging area at the water surface is unbroken, and large enough to prevent prim ing.
Longer gas travel through two passes of heavy gauge tubes is a plus value in secondary heating surface that assures greater fuel savings.
Optional--wrap-around steel jacket with mineral fiber in sulation.
Rapid circulation m wide, free waterways sweeps steam bubbles up without turbu lence to the unbroken disen gaging area at the water line.
Large, high firebox provides plenty of space for complete, economical combustion.
Exceptionally sturdy steel base is reversible for front or rear firing.
Crown sheet arched upward affords greater height for bet ter combustion. Also it is self draining and cleaning.
